Mapping the efficiency of ocean alkalinity enhancement
We developed a tool to explore a new dataset that makes it easier to see how the efficiency of ocean alkalinity enhancement varies around the world, in collaboration with [C]Worthy.

Crediting challenges when carbon removal comes with avoided emissions
Some carbon removal projects also result in avoided emissions. This is good for the climate, but can pose challenges for individual projects that are trying to earn carbon removal credits.

Analyzing initial offset disclosures under California’s AB1305
Beginning in January, California law AB1305 will require companies to disclose which offsets they use. An analysis of early data, voluntarily released before the law takes effect, demonstrates that these disclosures are powerful, but also highlights the opportunity for improvements around discoverability and usability.

Mapping the efficiency of ocean alkalinity enhancement
Increasing the alkalinity of the ocean can help increase CO₂ absorption. But the same techniques won’t lead to the same outcomes everywhere. We collaborated with [C]Worthy to build a tool that will make it easier to see where ocean alkalinity enhancement is most efficient.

Climate risk companies don’t always agree
Models broadly agree that climate change is affecting risks. But when it comes to assessing danger for individual addresses, the results can differ significantly.

The first offset credits approved by a major integrity program don’t make the grade
Initial results from the ICVCM assessment process highlight the challenges of reliably identifying high-quality offset credits.

Fire threatens the integrity of California’s forest offset program
The state’s cap-and-trade system depends on forest offsets. But forests burn. And the buffer pool isn’t robust enough to protect the system.

Policy Brief
The voluntary carbon market is gearing up to sell corn ethanol CCS projects as carbon removal because they store biogenic CO₂. We explain why this logic falls short.

Carbon offsets are incompatible with the Paris Agreement
For carbon offsets to support temperature stabilization under the Paris Agreement, nearly everything about them must change.

Using remote sensing to quantify the additional climate benefits of California forest carbon offset projects
An ex post analysis shows that credited carbon sequestration in California projects is likely non-additional. These findings illustrate the importance of using dynamic baseline controls to credit carbon.
